The Prototype Gamble

The maintenance bay of Sub-level 4 smelled of ozone and scorched hydraulic fluid. Kaelen Vane stood beneath the Iron Lung, his hands slick with grease. Above him, the overhead rail groaned as a swarm of automated maintenance drones descended, their optical sensors pulsing a rhythmic, predatory red. They weren’t here to repair; they were here to harvest.

“Unauthorized modification detected,” a synthesized voice boomed, echoing Overseer Thorne’s clipped, sterile tone. “Pilot Vane, your frame is flagged as a system anomaly. Stand clear for mandatory reclamation.”

Kaelen ignored the warning, his fingers flying over the Iron Lung’s exposed chest cavity. He had seconds before the magnetic clamps engaged. He jammed the jagged, black-box prototype module into the open port. It didn’t fit—the housing was too small, the pin configuration a relic of a dead era—but he forced it, the metal screaming in protest as he bypassed the safety interlocks with a shunt wire pulled from his own family’s encrypted logs.

“Override code: Vane-Alpha-Nine,” he whispered, his heart hammering against his ribs.

The drones froze, their red lights flickering into a confused amber. The Iron Lung shuddered, the prototype module drawing power directly from the frame’s core. The machine didn’t just wake up; it roared. The cooling fans spiraled into a high-pitched whine that set Kaelen’s teeth on edge. It was a gain, yes—but the heat spike on his diagnostic display was already climbing into the red.

Inside the cockpit, the air was suffocating. Kaelen tapped the haptic interface, his fingers dancing over the prototype’s feedback loop. The Iron Lung’s output was erratic, a violent pulse that threatened to melt the frame’s internal conduits. He checked the diagn
